Need some help with the ADF5901 AUX/AUX BAR outputs to drive the ADF4195 REF-IN A/REFIN-B inputs.
When the ADF5901 AUX/AUX BAR outputs to drive the ADF4195 REF-IN A/REFIN-B inputs diffrentially on a PCB
at 12GHz rate by DC-cutting with two 22pf caps,
Q1: Should a 200 ohm micro-strip line technique be used on the PCB?
( "200 ohm" comes from the data sheet electrical specification for the ADF5901 AUX/AUX BAR output imepedance.)
Q2: Is 22pf proper value for the DC-cutting caps? If not , what would be a better value?
Q3: If the answer to Q1 is "yes", what would be the limitation for the length of the PCB traces?
